Hans Selye is regarded as the founder of the theory of stress.
He developed the general adaptation syndrome (GAS) which describes how the body reacts to stress.

resistance - continued exposure to stress leads to higher metabolic response to offset the stress
exhaustion - continued exposure to stress can negatively affect the body and lead to health problems
